SPRING-MOTOR.

srEoI-FIcA'rIoN forming part of Letters Patent No. 712,432, dated october 2s, 1902.

@fuman nea .tpm s. 1961,

Serial No. 54,193.V (No model.)

Be it known that I, JOHN S. BAY, a citizen of 'i the United States ofiAmerica', residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Spring-Motors; and I do l declare the following to be a full, clear, and

Y exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the gures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in spring-motors, adapted to produce oscillating motion.

My improved motor is especially adapted for use in operating washing-machines; but

' fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a side elevation of my improved motor mounted on the top cover of awashing-machine. This cover is shown in section, while the oscillatory spindle provided with the forked arms for manipulating the clothes in a tank or receptacle (not shown) is shown in elevation. Fig. 2 is a top or plan view of the motor applied to the washer-top. Fig. 3 is asection taken on the line fr, Fig. 2. Fig. 4 is a section taken on the line y y, Fig. 2. Fig. 5 is a fragmentary View illustrating the ratchet and pawl used in connectionwith the main gear-wheel.`

The same reference lcharacters indicate the same parts in all the views.

Let the numeral 5 designate a suitable frame composed of two separated parallel members 5, which, as illustrated, are of the shape shown in Fig. 2, though it must be understood that the framework of the motor is not limited to this specific construction. Journaled in this framework is a shaft or l spindle 6, with which the part to be operated is connected. As shown in the drawings, a device 7 for manipulating the clothes in a tank or receptacle of a clothes-washer is shown. Upon the spindle or shaft 6 is made fasta balanced crank 8, one arm of which is connected at 9 with one extremity of a pitman 10, whose opposite extremity is connected with a crank-wheel 12 at a suitable distance from the center, as shown at 13. This crank-wheel is fast on a shaft 14, journaled in the frame. pinion 15, which meshes with'a gear 16, fast 4on a shaft 17, also journaled inthe frame- Work of the motor. Upon the hub of the gear `16 is formed a pinion 18, which meshes with a largerl gear 19,loose on a shaft 20. To this shaft is made fast a hub 2l, formed integral with a ratchet-wheel 22,which is engaged by a dog or pawl 23, pivotally mounted on the gear 19, as

`shown at 24. This dog is held normallyin engagement with the teeth of the ratchet by a coil-spring 25, carried by the gear 19. A power-spring 26 is coiled around the hub 2l, to which one of its extremities is made fast. rlhe opposite extremity of this power-spring is secured to the stationary framework of the motor, as shown at 27. To the eXteriorlyprotruding extremity of the shaft 20 is made fast a hand-crank 2S, whereby the shaft is turned in the direction indicated by the arrow in Figs. 2 and 5 to store power in the spring Whenpower is stored in the spring, the shaft may be locked against movement by the dog 29, mounted on the frame and capa- 3 ble of such adjustment that it may be brought into the path of the hand-crank to lock the To this shaft is made fast a i released by turning the dog onits pivot. The

recoil of the spring when the hand-crank is released turns the shaft 20 i n the direction opposite that indicated bythe arrow inFigs. 2 and 5 and turns the gear 19 in a corresponding direction through the instrumentality of the ratchet 22 and the dog 23. The rotation of the Wheel 19 imparts increased speed to the wheel 16 by virtue of the pinion 18, and

the wheel 16 in turn imparts a still more rapid motion to the shaft 14 by virtue of its IOO engagement with the pinion 15. The rotation of the shaft 14 operates the crank-wheel 12, which communicates an oscillatory movement to the shaft or spindle 6 through the instrumentality 0f the pitman 10 and the balanced crank 8. This oscillating motion results from the fact that the distance between the axis of the wheel 12 and the point where the pitman is connected with said wheel is less than the length of the'crank-arm of the balanced crank with which the opposite extremity of pitman is connected. Hencel before the balanced crank, with which the opating-spindle 6 is connected, can complete its revolution it is given a reverse or backward movement, the result being an oscillating action, which is required for operating the forked device 7 of the clothes-Washer.

The speed of the machine is controlled by a tension device consisting of a coil-spring 30, surrounding the protruding extremity of the shaft 14 and bearing against a washer 3l at one extremity and against the frame of the machine at the opposite extremity. The protruding extremity of the shaft 14 is threaded to receive a nut 32, which when screwed down upon the washer causes the latter to bear with more or less force upon the spring, which is correspondingly forced against the frame. The friction resulting from this pressure as the shaft 14 turns regulates the speed of the mechanism. The tension-n ut when adjusted is locked from turning on the shaft by a removable key 33, inserted in registering grooves formed in the adjacent parts of the nut and shaft. The additional arm of the balanced crank, or the arm opposite that with which the pitman is connected, overcomes any tendency that might otherwise exist for the crank-wheel, pitman, and crank to stop on a dead-center.

Having thus described my iuveution,wl1at I claim is- 1. In a spring-motor, the combination of a main shaft, a spring coiled around said shaft and made fast thereto at one extremity, its opposite extremity being made fast to the frame, a ratchet-wheel fast on the shaft, a gear-Wheel loose on the shaft, a spring-held dog mounted on the gear and engaging the teeth of the ratchet, the arrangement being such that as the shaft is rotated in response to the recoil action of the spring, the ratchetwheel engages the dog and turns the gearwheel; a second shaft journaled in the frame, a pinion fast thereon and meshing with the gear on the main shaft, a gear also fast on the second shaft, a third shaft also journaled in the frame, a pinion fast thereon and meshing with the gear of the second shaft, a crank- Wheel also fast on the third shaft, a spindle, a device to be operated made fast to the spindle, a crank fast on said spindle, and a pitman connecting the crank-Wheel With the crank of the spindle, the arrangement being such that as the crank-wheel rotates, rotary motion in reverse directions will be imparted to the spindle to which the part to be operated is attached.

2. The combination with a suitable frame and a device to be operated, a spindle to be oscillated, said device being attached t0 the said spindle, a crank on the spindle, a crankwheel, a pitman connecting the'crank and crank-wheel to give the crank oscillating motion while the crank-wheel rotates, a shaft on which the crank-Wheel is made fast, and protruding from the frame, a spring coiled around the protruding extremity of the crank- Wheel of the shaft, a nut screwed upon the said shaft to compress the spring whereby the speed of the mechanism may be regulated and controlled, a main shaft, a power-spring surrounding the main shaft, one extremity of said spring being connected with the shaft, and the other extremity with the frame, a ratchet-wheel fast on the shaft, a gear-wheel loose on the shaft, a spring-held dog mounted on the gear and engaging the teeth of the ratchet, the arrangement being such that as the shaft is rotated in response to the recoil action of the spring, the said wheel engages the dog and turns the gear-wheel, a second shaft journaled on the frame, a pinion fast thereon and meshing with the gear on the main'shaft, a gear also fast on the second shaft, and a pinion fast on the crank-wheel shaft and meshing with the gear of the second shaft, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

JOHN S. BAY.
